A network diagram shows a DNS server, a web server, and an email server behind a firewall. The firewall has rules that allow inbound traffic to the DNS server on UDP 53, to the web server on TCP 443, and to the email server on TCP 25. Which additional rule is needed to allow clients to resolve domain names using DNS?

Allow inbound TCP 25 to the DNS server.

Allow inbound UDP 443 to the DNS server.

Allow inbound TCP 53 to the DNS server.

Allow inbound UDP 53 to the DNS server (already present) — no additional rule is needed.

A topology shows an external client accessing a company's web server via HTTPS. The firewall rule allows inbound TCP 443 to the web server. The web server also needs to be accessed via HTTP for redirect to HTTPS. Which additional firewall rule is required?

Allow inbound TCP 80 to the web server.

Allow inbound TCP 443 to the firewall.

Allow outbound TCP 80 from the web server to the client.

Allow inbound UDP 443 to the web server.

A network diagram shows two switches connected by two separate links. The switches are configured with Spanning Tree Protocol (STP). What is the purpose of having two links between the switches?

To provide link redundancy while STP prevents loops

To connect two different VLANs on separate links

To allow the switches to route between each other

To double the bandwidth by using both links simultaneously

In a topology diagram, a client PC is connected to a switch, which is connected to a router, which is connected to the internet. When the client sends a request to a web server on the internet, what is the correct order of devices the data passes through?

Client → Router → Switch → Internet

Client → Switch → Internet → Router

Client → Switch → Router → Internet

Client → Internet → Router → Switch
